> Or will Putin die or get overthrown and we go back to normal

That's a big if... he might have someone lined up

[version_five]

Yes good point, there is also the option that his successor maintains this program and nothing change or somehow it gets more dangerous

[quantified]

There ought not to be "normal" like we were pretending it to be since Putin came to power. Unlikely to see another Gorbachev. Either someone he picked or someone who wants to be him are likely the next century's leaders. The West will simply not be able to trust them.
